Description
5 Bbl Isobaric Craft Beer Fermenter with Integrated Cooling
We build this 5 bbl fermenter for breweries that need reliable temperature control during active fermentation. The isobaric design allows you to maintain pressure while transferring or packaging, which matters when you\’re chasing consistent carbonation without a separate brite tank. The cooling system is not an afterthought—it\’s built into the jacket and sized to handle the heat load of a 5 bbl batch during peak fermentation.
Construction and Materials
The tank body and cone are formed from 304 stainless steel, with 316L available on request for aggressive cleaning regimes or high-chloride water. Interior welds are ground flush and passivated. Exterior welds are left as-is unless you specify a polished finish for washdown areas. The dimpled cooling jacket covers the cone and lower cylinder. We use a 2-inch polyurethane insulation layer to minimize condensation and glycol consumption.
Cooling and Pressure Management
Glycol flows through the jacket via 1-inch NPT or tri-clamp ports. A pressure relief valve is set at 15 psi by default; if you plan to spund or carbonate in the fermenter, we can supply a higher-rated valve to match your process. The manway is a 16-inch top-hinged door with a full gasket seal. CIP is handled through a rotating spray ball on the top dish, with the drain port at the cone tip.
Practical Considerations for Selection
Small brewpubs often run 5 bbl tanks as their primary fermenters, sometimes with a single tank dedicated to each flagship beer. Commercial breweries may use them as pilot or blending tanks. The decision usually comes down to batch size and how many turns you need per week. If you\’re brewing high-gravity beers or using lots of dry hops, allow extra headspace—about 20–25% above the batch volume.

Frequently Asked Questions
Can I carbonate in this fermenter? Yes, if you specify the higher-pressure relief valve and ensure all fittings are rated accordingly.
What glycol chiller size do I need? For a single 5 bbl tank, a 1/2 HP chiller is usually sufficient; for multiple tanks, size the chiller for the total heat load.
Is the tank suitable for CIP? Yes. The spray ball and cone drain allow for effective clean-in-place cycles.
How do I connect the cooling system? We provide 1-inch tri-clamp ports for glycol supply and return, with flow direction marked on the jacket.
Tell us your batch size, beer type, number of fermentation tanks and available space. We can recommend the tank volume, cooling area and configuration for your brewery.

Although there were a few minor issues, thanks to Polly’s help, it looks brilliant and has brought my little distillery quite a few new customers.
Very good！！I see now in my texting to you that in my excitement over having the installation here in the USA I totally forgot to give you and the company of ACE a very big compliment on the quality of the whole Installation!! It all looks fabulous and the way you packed it in the container was extraordinary!! I am very impressed with your company and want to say a big thank you to everybody who worked on my order!!
We have been using this still for a few batches now making whiskey, gin and a few other spirits and we are very happy with the results so far. The gear works well and gives good control during distillation. The spirit comes out clean and consistent from batch to batch and we have gotten the flavor profile we were looking for. It has also been easy to operate and maintain. It has been a great addition to our distillery and I’d definitely recommend it to other craft distillers looking for reliable equipment.”
Polly is the man! I highly recommend him and this products they produce! I’m very satisfied. she communicates very well and the quality of workmanship is excellent! Shipping was exceptional. Thannks Polly and team
